High resolution electronic spectroscopy of Kr center dot OH/D and an empirical potential energy surface

The high resolution laser-induced fluorescence spectra of the Kr.OH van der Waals complex and its deuterated analog are reported. The rotational analy sis provides information about the observed fine, hyperfine, spin-rotation, and parity interactions in these two complexes. The molecular parameters a llow a direct comparison with previously reported results on the analogous Kr.SH/D complexes. Additionally, lower resolution scans have revealed vibro nic bands that have not been reported in the previous work of Fei, Zheng, a nd Heaven [J. Chem. Phys. 97, 1655 (1992)],while high resolution results of the Kr-86.OH/D, Kr-84.OH/D, and Kr-82.OH/D isomers confirmed the previous vibrational quantum number assignment. The results of the high resolution a nalysis are used in conjunction with measured vibrational intervals to deve lop an empirical potential energy surface for Kr.OH/D. This is compared to the recently reported potentials by Korambath et al. [J. Chem. Phys. 107, 3 460 (1997)] for the other R.SH/D (R = Ar, Kr) complexes. (C) 1999 American Institute of Physics.
